In fact, this problem has been defined for a long time, because someone has done such an experiment. When the roots of plants lack water, the photosynthesis of leaves stops. At this time, if the roots are watered, it usually takes several minutes to flow to the leaves. However, at the same time of watering, photosynthesis resumed immediately. Later, many experiments proved that there is a system similar to animal nerve in plants, which is all over the body.

In this plant regulation system, people actually isolate a primitive problem, which is owned by any nervous system. About 198 1 manderley, a plant physiologist at Stanford university in the United States, found that some plants have optical fiber systems that can transmit light up and down in tissues. The method used is the same as that used by telephone companies to transmit many calls.

By touching in a completely opaque honeycomb hut, she then irradiated the cut end or uncut side of the plant tissue with a beam of He-Ne laser, and then measured the transmitted light at the cut end with a row of photosensitive devices. This kind of light beam can transmit the original light-type vacuum image of more than 2.5 cm along the plant stem and even bend. Darwin actually said that in order to protect the body from low temperature, turn off the leaves at night and let them sleep.

However, Owen said in the world authoritative biological clock theory in the1970s that in order to prevent the biological clock from resetting the moonlight due to strong light, whether plants sleep to avoid low temperature at night or to avoid bright moonlight at night is lack of experimental evidence. That is to say, people cannot cultivate leguminous plants that do not sleep or open their leaves. Until now, scientists can finally stop plants from resting.

How much smarter it is than we thought, and how powerful the thinking ability of plants is, this question is explained here today.
